Simplify's Take

What believers are saying

  • April 2026 brought a $149.7 million DLA award modernizing Reagan Test Range through 2031.
  • Radiance won DARPA MICA and $5.85 million biology contracts in 2026, broadening R&D.
  • April 2026 promotions of Hammett and Lithgow strengthened operations and growth leadership.

What critics are saying

  • PeopleTec sued Radiance in March 2026 in Alabama, signaling intellectual-property friction.
  • The $149.7 million Reagan Test Range contract runs five years, concentrating revenue on one program.
  • One lost sole-source recompete at Reagan Test Range would gut a major growth engine.

What makes Radiance Technologies unique

  • Radiance pairs directed-energy engineering with intelligence and cyber work, spanning DoD missions since 1999.
  • Its 2025 Verus Research acquisition deepened microwave, radar, and electronic-warfare capabilities.
  • Employee ownership and veteran leadership from Bill Bailey and Darien Hammett align execution.

Air Force releases draft RFP for TETRAS III R&D support IDIQ.

Air Force releases draft RFP for TETRAS III R&D support IDIQ. * The Air Force has released a draft RFP for TETRAS III, the planned recompete of its test and evaluation contract vehicle * The IDIQ will cover instrumentation, infrastructure and technical expertise for testing fifth- and sixth-generation weapons and cyber systems * An earlier RFI suggested the recompete could be worth up to $20 billion over a decade The Department of the Air Force has issued a draft request for proposals for Test and Evaluation Technologies for Ranges, Armaments and Spectrum III, opening industry review of the planned multiple-award recompete of its TETRAS contract vehicle. Posted Thursday on SAM.gov as a special notice serving as the official presolicitation, the draft RFP gives prospective offerors an early look at the indefinite-delivery/indefinite-quantity acquisition before a formal solicitation, anticipated on Oct. 27. The Air Force Test Center at Eglin Air Force Base, Florida, is running the procurement. The competition will be conducted on a full and open basis, with security requirements ranging from confidential to top secret. As the Air Force modernizes how it tests next-generation weapons and cyber systems, service leaders are also charting the broader path for emerging technology across the air and space domains. They will share those strategies at the Potomac Officers Club's 2026 Air and Space Summit on July 30, where Gen. John Lamontagne, vice chief of staff of the Department of the Air Force, joins top Space Force officials and industry executives for a full day of keynotes, panels and networking. Register now to secure your spot. What will TETRAS III cover? According to the draft statement of work, TETRAS III will supply airborne and range instrumentation, infrastructure, facilities, and technical expertise supporting the 96th Range Group and other Department of War organizations as they develop and modify test and evaluation systems for fifth- and sixth-generation weapons and cyber systems. The scope spans testing of weapon systems; command, control, communications, computers, cyber defense, combat systems, intelligence, surveillance and reconnaissance - or C6ISR - platforms; and electronic combat systems. Contractors will design, fabricate, integrate and install specialized hardware, software and prototypes for air, ground, sea and space applications, with required expertise covering hypersonics, directed energy, autonomy, artificial intelligence, electromagnetic spectrum testing, countermeasures, cybersecurity assessments and aircraft survivability equipment. The statement of work emphasizes open-architecture designs that are modular, scalable and reusable, with compliance with the Test and Training Enabling Architecture where practical. The vehicle excludes advisory and assistance services. Work is expected to be performed worldwide. How can industry weigh in on the potential TETRAS III contract? Companies have until June 26 to submit questions, comments and feedback. The government plans to post its responses by July 13. How big could the TETRAS recompete be? TETRAS III follows the $1 billion TETRAS II vehicle, which the Air Force awarded to 46 companies in June 2023 after receiving 49 bids. Awardees on that previous contract, including Booz Allen Hamilton, Leidos subsidiary Dynetics, Jacobs, Kratos Defense & Security Solutions, Saab, Serco, Torch Technologies, and Radiance Technologies, compete for delivery orders to build and upgrade test systems and facilities, with work running through Dec. 31, 2028. The service signaled the scale of its ambitions for TETRAS III in an April 2025 request for information, which described a recompete structured with a five-year base period and five-year option period valued at up to $20 billion if all options are exercised.
